wna'rnnn s'rrm on BUFFER ronwmnow sasnnsl Application filed September This invention'relates to window Sashes and has for its object a'bufier or weather stripfor engaging the window S111 and read- I i ily conforming tov all unevennesses in the sill and to sills of different inclinations.

The invention consists in-the novel features and in the combinations and constructions hereinafter'set forth and claimed. I

In describing this invention, reference is had to the accompanying drawing which is a transverse sectional view through the lower rail of .awindow sash, the rail being shown in perspective.

This, weather strip comprises a body at tachable to the lower edge of the lower rail of the window face and having downwardly and inwardly extending lipswhieh meet or j which tend to meet along the apex or me-' I dium line of the strips when the strip is compressed by the sash against-thesill.

l'designates the lower rail of a window sash and as here shown it is formed up of sheet metal and is open'at its lower edge i and provided with inturned flanges 2 at its lower edge.

3 designates the weather strip or buffer, which is here shown as attached to the lower rail by interlocking therewith and having lengthwise grooves 4 at opposite sides thereofwhich interlock with t e inturned flanges 2 upon endwise sliding movement of the weather strip. The body of the strip below the edge of the race is preferably semi-cylindrical, that is, it is semi-discoidal in cross section and the two inwardlyextending lips 6' are provided by forming the strip with a lengthwise tubular passage 7 and a slot or a slit 8 extending radially of the semicylindrical portion of the strip and opening through the apex line of the strip and into the passage.

When the sash is brought down onto the sill designated 10, these two inturned-lips will compress toward each other and conform to unevennesses and also to the in clination of the sill and will form a weather proof joint between the sash and the sill.

The flanges 2 support the ballot or weather strip and receive the thrust thereof 11,1925. sca No. 55,764.

and are f located on opposite sides of the apex lineof the bufier or the line where the bufl'er'engages the sill. Owing tothe relative location of the supporting means for the buffer and the line of engagement of the buffer and the sill,'t he lips 6 compress toward each other when the bufl'er compresses. What I claim is:

v1. A window sash comprising a lower rail, a weather strip for the lower rail com.-

prising a body portion formed ,with down- 1 wardl and inwardly extending marginal 2. A weather strip for the'lower rails of lips, t e lips being arranged to move toward .each other at their edges during compression of the strip.

window sashes comprising a body extend) ing lengthwise of the edgeof the lower rail,

the body being semi-cylindrical and ar ranged with its 'flatbase toward-theedge of the rail, the body being-formed with a lengthwise passage openingv through the apex of the semi-cylindrical surface of the body forming the body'with. inwardly compressible lips..

window sashes comprising av semi-cylindrical body arranged with its base toward the edge of the sash, the body being formed with a lengthwise tubular passage and with .a radial slit opening fromsaid passage through the apex of'the semi-cylindrical surface. I I p 4. A window sash comprising a lower rail, a weather strip for the lower rail comprising a body portion formed with downwardly and inwardly extending lips, the lips being arranged -to move toward each other "at their edges during compression of the strip, the body being formed with lengthwise grooves on opposite sides thereof and the lower rail of the sash being formed ,75 :3. A weather strip for the lower rails of I with flanges interlocked with the grooves.
